(ci. sli- 26) My invention relates to driers, and has particuconcentrically disposed, annularly arranged openlar reference to driers for use in drying hair, or ings 44,' communicatingl with an annular passage the hands, or the like, and the principal object of y.15 defined by thevouter surface of `the shell2v6 and my invention is to provide a new and improved the inner surface of the casing I5, this passage'l5v 5 drier of this type.

The casing I5 is The ring member 29 also has a rearwardly forwardly dared as at I1, offset at its forward exprojecting flange 46 providing a support for lamp 30 tremity as at I8, and provided with a substansockets 41 supporting therapeutic lamps 48. At tially annular extension I9 having a beaded forthe outer sides of the lamps 48 the ring member ward edge 20. 29 is provided with a shoulder 49 forming a seat A motor 2I is disposed within the casing I5, for the edges of a screen 5I), detachably secured having a supporting block 22, affixed thereto by in position by screws 5I tapped into the shoulder 35 bolts 23, provided with a threaded stud 24 pro- 49. Attention may at this point be directed to jecting through a suitable aperture in the spider the fact that the lamps 48 are located inwardly I0, and secured by a nut 25. of the inlet 42, in the inlet stream of air and are An inner shell 26 is secured to the motor casexposed toward said inlet and toward the object 'ing 2| by screws 21, extends forwardly in spaced to be operated upon, thereby radiating light and 40 relation.. with reference to the wall of the casing heat emanations directly upon the subject, while I5, terminating at 80 and secured by screws to a heat emanations therefrom heat the surrounding shoulder 28 of a supporting ring member 29, and air, and the air thus heated is entrained in the a layer 39 of insulating material interposed beincoming stream of the recirculating air, joining 4.3 tween the end of the shell 26 and the shoulder such stream where the air is already heated, and 45 28. The outer periphery 3| of thering member augmenting the heat, in contra-distinction to all 29 supports the forward portion of the casing I5, other devices of which I have knowledge, wherebeing arranged in front of the offset I8, and a in a direct non-recirculating current of air is layer 32 of insulating material interposed beblown over the source of radiant energy and distween the outer periphery 3| of the ring member charges from the casing, thereby rapidly dissi- 29 and adjacent inner surface of the extension pating the heat generated thereby. l

I9. The ring member 29 has a central inlet open- The ring member 29 is also provided with a foring 42 communicating with the interior of the wardly projecting iiange 52, supporting the rear shell 26, annularly arranged outlet openings 43 flange 53 of a flared substantially funnel-shaped also communicating with the shell 26, and outer, extension 54, screw bolts securing the flange 5 I3 oi the extension 54 to the ring 28. The extension 54 terminates short of the outer end of the extension |8 as shown, and by reason of its outwardly :dared shape, forms with the adjacent wall of the extension |9 a converging passage 56 into which the air from the interior of the shell 26 and the passageway 15 discharges. Disposed in line with the restricted outer end of the annular passage 56 and forwardly of the end of the extension 54, is an annular deiecting rib 51, carried by the extension I9 adjacent its outer end, and secured by rivets 58, and in the passage 56 are vanes 59 inclined outwardly in opposite directions with reference to the axis ofthe fan, each comprising a ilange 68, secured to the outer surface of the extension 54 by rivets 6|, and an upstanding ange 62 providing a vane for distributing the air with reference to the deflecting rib 51.

As shown in Figure the circuit for the motor 2| comprises a branch 63 leading to the line wire 64, and a branch 65 leading to an arcuate terminal 66 of a switch 61 having a lever 68 connected with the line wire 69. The lamps 48 are interposed in a circuit including a branch 10 ytapped in the motor circuit and communicating also with the line wire 64 through the branch 63 of the motor circuit; the other branch 1| of the lamp circuit leads to a terminal 12 of the switch 61, adapted to make connection through the lever 68, contact 66, branch 65, and branch 63 with the line wire 64. The heating coil 33 is interposed in the branches 10 and 1|, in parallel with the lamps 48. A resistance coil 13 is connected with the branch 1| of the lamp circuit and with a branch 11leading to a terminal 14 of the switch 61. With this arrangement engagement of the lever 68 only with the contact 66, the motor can be energized without operation of the lamps 48, heating coil 33 or resistance 13. Movement of the lever 68 clockwise, remaining in engagement with the terminal 66, and coming into engagement with the terminal 14, in'addition to the motor 2|, brings about energization of the lamps 48, the coil 33 and resistance 14. Further movement of the lever 68 until in engagement with the terminal 12, cuts out the resistance 13 as will be appreciated, while maintaining energization of the motor 2|, lamps 48, and heating coil 33.

When the motor 2| is operating to rotate the fan 38, air is drawn inwardly 'through the extension I9, thence entering the extension 54, passing through the screen 58, heated by the coil 33, when energized, thrown off by the fan along its circumferential periphery, thence following the contour of the shell 26, again passing over the heating coil 33, and discharging through the openings 43 in the ring member 28, thence passing through the converging annular passage 56, being distributed by the vanes 58, and deflected by the deiiecting rib 51, a large portion of the air thus deilected again passing inwardly into the funnel-shaped extension 54, and hence recirculating.

Owing to their peculiar disposition the lamps direct their energy toward the inlet 42 and the object arranged in the operating chamber, and in a direction opposite to the travel of the air, the energy so generated being thus conserved, in contradistinction to those structures in which the energy from the lamps is directed in the same direction as the travel of the air, and is rapidly dissipated.

Underv these circumstances it will be understood that the embodiment described accompllshes at least the principal object of the invention; however, it will be apparent to those skilled in the art that thev invention is susceptible of other uses than those herein described and may 5 be variously changed and modied, all without departing from the spirit of the invention; accordingly it will be understood that the embodiment herein described and shown is illustrative of only one embodiment of the invention, and 10 that the invention is not limited thereto.
